Gas Piping
AWARNING
Make sure the gas supplied is the same type listed on the
model rating plate. The inlet gas pressuremust not exceed
10.5in.water column(2.6kPa) for natural gasor 13 in.water
column (3.2kPa) for propane(I-R) gas.The minimum inlet
gas pressurelisted on the model rating plate is for the pur.
poseof input adjustment.
• AWARNING I
If the gascontrolvalveis subjected to pressures exceeding_A I
pound per squareinch(3.5kPa), the damage to the gascon-
tro valvecouldresult n a Ereor exploson from eakinggas.
There must be a minimum of 6" clearance between single wall
vent pipe and any combustible material. Fill and seal any clear-
ance between single wall vent pipe and combustible material
with mortar mix, cement, or other noncombustible substance.
For other than single wall, follow vent pipe manufacturer's clear-
ance specifications. To insure _"tight fit of the vent pipe in a
brick chimney, seal around the vent pipe with mortar mix
cement.
AWARNING [
If the main gasline shutoffserving all gasappliances is used,[
also torn "off" the gasat each appliance.Leaveall gasappli-

A gas line of sufficient size must be run to the water heater.
Consult the latest edition of National Fuel Gas Code ANSI
Z223.1, also referred to as NFPA 54 and the gas company con-
cerning pipe size.
There must be:
• A readily accessiblemanual shut off valve in the gas supply line
serving the water heater, and
• A drip leg (sediment trap) ahead of the gas control valve to hdp
prevent dirt and foreign materials from entering the gas control
valve,
• A flexible gas connector or a ground joint union between the
shutoffvalve and control valve to permit servicing of the unit.
Be sure to check all the gas piping for leaks before lighting the
water heater. Use a soapy water solution, not a match or open
flame. Rinse offsoapy solution and wipe dry.

Standard Models are for installation up to 3,300 feet above sea
level.
High Altitude Models are for installation from 3,300 to 5,500
feet above sea level.
Ifa standard model is installed above 3,300 feet or a high altitude
model is installed above 5,500 feet, the input rating must be
reduced at the rate of 4 percent for each 1,000 feet above sea level.
Contact your local Sears Service Center or gas utility for further
information.
AWARNING
The appliance and its gas connection must be leak tested
